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

Evidence for Biofilm-induced Self-sustaining Meandering Channels
No full textThis dataset contains all processed materials generated from three independent experimental replicates designed to investigate how synthetic biofilm alters river channel morphodynamics. The dataset includes:
1. Top-view images and videos
High-resolution time-series images (.png) and videos (.mp4) documenting river evolution throughout every flow cycle. These files capture the transition from a braided channel to a single-thread meandering, reproducing different aspects of natural rivers such as cutoff events, bank migration, and channel narrowing as biofilm cohesion develops.
2. 3D topography
Laser bed elevation measurements were collected during low cycles. These data allow for quantification and reconstruction of river evolution.
3. YOLO machine learning
A trained YOLO segmentation model for automated river morphology detection, including:
Model weights and scripts for running and extracting channel masks, centerlines, and additional metrics.
4. Processed datasets
Pre-computed .csv files summarizing:
Sediment transport measurements.
Channel width, depth, and sinuosity.
Erosion and deposition maps.
Together, these datasets provide complete and reproducible information on how synthetic biofilm influences sediment transport and channel patter evolution, enabling analysis, and broader use in geomorphology and planetary analog research.This dataset presents the complete morphological evolution of a braided river channel transitioning into a single-thread meandering channel under the influence of synthetic biofilm. It includes data from three independent experimental replicates, all conducted these experiments in a large flume at the St. Anthony Falls Laboratory, where a sand bed, constant sediment feed, and alternating high and low flow cycles were used to reproduce natural river dynamics.
The dataset contains high-resolution top-view images and videos documenting channel evolution during each flow cycle, 3D topographic measurements collected using a laser scanner, and machine learning including a trained YOLO segmentation model (weights and analysis scripts) for detecting and tracking channel morphology.
Together, these data provide comprehensive and reproducible evidence of how synthetic biofilms modify sediment transport, channel mobility, and river morphodynamics, ultimately promoting the emergence and persistence of meandering river patterns across all three replicates.This study is supported by National Science Foundation CAREER Award EAR 2236497 and Office of Navy Research Grant N00014‐23‐1‐2559.Cúñez, Esteban A; Yang, Judy Q.

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
