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
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
Evaluation of parameter setting for two GIS based unit hydrograph models
For watersheds where flow data are unavailable, the geomorphology-hydrology relationship can be used to estimate the direct flow response to excess rainfall. Two of the most common approaches used to compute this response are Geomorphological Instantaneous Unit Hydrographs (GIUH) and Spatially Distributed Unit Hydrographs (SDUH). In the former, the hydrograph is determined from the input of morphometric parameters and an average channel velocity, where in the latter a time-area relationship is used to compute the hydrograph. Generally, both approaches involve an estimate of velocity to parameterize the Unit Hydrograph (UH), however, information on this parameter is generally limited for watersheds where these methods are most appropriate, when there is no flow data to derive the UH directly. The aim of this work is to investigate if the velocity parameters involved in GIUH and SDUH methods can be estimated directly from watershed characteristics, and allow these methods to be applied in ungauged watersheds. Four watersheds in southern Australia with daily flow records have been considered, to allow the observed direct flow response to be determined. It was found that both approaches could be calibrated to accurately represent the expected response for all four watersheds considered. The SDUH model implemented considered hillslope and channel flow processes separately, which allowed the velocity parameters involved to be estimated from the watershed using Manning's equation. However, the GIUH model combines these flow processes into one average velocity parameter, and due to this averaging a relationship between the calibrated value and the watershed characteristics could not be determined. The results suggest that the SDUH model can be directly parameterized for a given watershed in the absence of flow data, however, further work is required to investigate if the relationships proposed are suitable for a wider range of watersheds. © 2010 Elsevier B.V.M.S.

Dispelling the Myths Behind First-author Citation Counts
We 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
