    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Full text link
    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

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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

    Globus Automate: A Distributed Research Automation Platform

    No full text
    Exponential increases in data volumes and velocities are overwhelming finite human capabilities. Continued progress in science and engineering demands that we automate a broad spectrum of currently manual research data manipulation tasks, from transfer and sharing to acquisition, publication, indexing, analysis, and inference. To address these needs we are developing a fullfeatured distributed research automation platform, Globus Automate. Globus Automate is designed to increase productivity and research quality across many science disciplines by allowing scientists to offload the management of a broad range of data acquisition, manipulation, and analysis tasks to a cloud-hosted distributed research automation platform. Globus Automate fills an important and previously un-met need in research cyberinfrastructure (CI). It addresses the problem of securely and reliably automating, for many thousands of scientists, sequences of data management tasks that may span locations, storage systems, administrative domains, and timescales, and integrate both mechanical and human inputs. This is a different problem to that of programming parallel workflows, as handled by HTCondor [1], Parsl [2], and Pegasus [3], or building integrated data management systems, as handled by iRODS [4], Rucio [5], and business rules engines [6]. IFTTT is more similar, being simple, SaaS, and extensible to new events and actions, but it does not integrate with CI security or resources, or handle sequences of actions. Our Automate implementation leverages Amazon Web Services. It uses Step Functions for flow automation, Simple Queue Service for event delivery, Reliable Database Service for persisting state, and Lambda for managing action executions. These mature, cloud- hosted services simplify delivery of a reliable, scalable service, allowing us to provide advanced capabilities to many scientists at modest cost. The Automate service enables the detection of events at Globus endpoints and other sources; the execution by the cloud-hosted Globus Automate engine of user-supplied automation flows either manually or as a result of data events; and the invocation of actions from those automation flows, including actions provided by Globus endpoints and services. The service is easily extensible by anyone via the definition of new events and actions to meet the needs of specific communities.We have deployed Globus Automate to simplify and accelerate research for a diverse collection of scientific domains, from Materials Science to Cosmology, and scientific instruments, including light source synchrotrons and scanning electron microscopes. In this talk will present Globus Automate, its architecture and prototype implementation. We will frame this talk in the context of a real-world neurocartography use case in which Globus Automate is used to perform a complex image reconstruction and analysis pipeline using data obtained from Argonne National Laboratory's Advanced Light Source. This flow involves a complex, distributed, analysis and publication process to perform data-driven analyses of large unsectioned brain volumes, generated at > 20GB per minute, using HPC resources.References[1] Michael J Litzkow, Miron Livny, and Matt W Mutka.

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
