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
Experimental approaches for size-based metal speciation in rivers
No full textA review of the different methodologies employed to fractionate and characterize riverine suspended particulate
matter is presented. The importance of size-based metal speciation is underlined and the possibility of studying
it by the Sedimentation Field Flow Fractionation (SdFFF) technique is illustrated. The studies on the metal
load in river Suspended Particulate Matter (SPM) performed over the last ten years are critically reviewed
focusing on the different methods employed to collect, concentrate and size-fractionate samples. The fact that
there is no homogeneity in methods and data collection in this field is underlined. Among the different
fractionation techniques, Field Flow Fractionation (FFF) methodologies have proved to be a good approach to
study the role of SPM in metal load and transport. The possibility of studying size-based metal speciation using
the SdFFF technique is presented and the importance of metal speciation in rivers is underlined
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
Characterisation of River Po particles by sedimentation field-flow fractionation coupled to GFAAS and ICP-MS
No full textA procedure for elemental composition determination of water-borne rixer particles (Po River) on both sizefractionated
and unfractionated submicron particles (0.1 1 lam) by graphite furnace atomic absorption spectroscopy
tGFAAS) and inductively coupled plasma-mass spectrometry (ICP-MSI is reported. Sample fractionation was
performed using sedimentation field-flow fractionation (SdFFF). The distribution of relative mass vs. particle size was
determined using UV detection. Fractions were collected over a narrow size range for scanning electron microscopy.
With this combination of techniques the mass, elemental composition, and shape distributions can be ~btained across
the size spectrum of the sample.
The size distributions of the major elements (A1, Fe) were determined by coupling both GFAAS and ICP MS
techniques to the SdFFF. The procedure was validated using a reference chty sample. Satisfactory agreement was
found between both the GFAAS and ICP MS aluminium signal and the UV detector signal. Some discrepancies were
observed in the Fe/AI ratios when comparing GFAAS and ICP MS. Thus further investigation is in order to fully
assess the role of SdFFF-ICP MS and SdFFF-GFAAS techniques for elemental characterisation of aquatic colloids.
Both GFAAS and ICP MS signals unambiguously indicate a significantly higher Fe content in the lower size range,
which is consistent with previous investigations.
Trace element levels in unfractionated Po River particles, determined by both GFAAS and ICP MS, show good
agreement. The high levels of Cu, Pb, Cr and Cd found associated with the colloidal particles underlines the signiticance
of the environmental role played by the suspended matter in rivers in both highly industrialised and intensively
cultivated areas
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
