  • Are elite journals declining? 

    Larivière, Vincent; Lozano, George A.; Gingras, Yves (Association for information science and technology, 2013-11-19)
    Previous research indicates that during the past 20years, the highest-quality work has been published in anincreasingly diverse and larger group of journals. In thisarticle, we examine whether this diversification has alsoaffected the handful of elite ...
  • Changes in publication languages and citation practices and their effect on the scientific impact of Russian science (1993–2010) 

    Kirchik, Olessia; Gingras, Yves; Larivière, Vincent (Wiley, 2012-03-28)
    This paper analyses the effects of publication language on international scientific visibility of Russia using the Web of Science. Like other developing and transition countries, it is subject to a growing pressure to “internationalize” its scientific ...
  • Comparing bibliometric statistics obtained from the Web of Science and Scopus 

    Archambault, Éric; Campbell, David; Gingras, Yves; Larivière, Vincent (Association for information science and technology, 2009-04-13)
    For more than 40 years, the Institute for Scientific Information (ISI, now part of Thomson Reuters) produced the only available bibliographic databases from which bibliometricians could compile large‐scale bibliometric indicators. ISI's citation indexes, ...
  • The decline in the concentration of citations, 1900–2007 

    Larivière, Vincent; Gingras, Yves; Archambault, Éric (Association for information science and technology, 2009-01-29)
    This article challenges recent research (Evans, 2008) reporting that the concentration of cited scientific literature increases with the online availability of articles and journals. Using Thomson Reuters’ Web of Science, the present article analyses ...
  • The effect of university–industry collaboration on the scientific impact of publications : the Canadian case, 1980–2005 

    Lebeau, Louis-Michel; Laframboise, Marie-Claude; Larivière, Vincent; Gingras, Yves (Oxford University Press, 2008)
    Previous research on university-industry collaboration in Canada concluded, using mean impact factors as a proxy, that the scientific impact of such research is not inferior to that of university research. Using field-normalized impact factors and ...
  • The effects of aging on researchers’ publication and citation patterns 

    Gingras, Yves; Larivière, Vincent; Macaluso, Benoit; Robitaille, Jean-Pierre (Public library of science, 2008-03-29)
    The average age at which U.S. researchers receive their first grant from NIH has increased from 34.3 in 1970, to 41.7 in 2004. These data raise the crucial question of the effects of aging on the scientific productivity and impact of researchers. ...
  • Financement, productivité et impact scientifique des chercheurs québécois selon le genre 

    Larivière, Vincent; Vignola-Gagné, Étienne; Villeneuve, Christian; Gélinas, Pascal; Gingras, Yves (Institut de la statistique du Québec, 2010)
  • The impact factor’s Matthew Effect : a natural experiment in bibliometrics 

    Larivière, Vincent; Gingras, Yves (Association for information science and technology, 2009-10-08)
    Since the publication of Robert K. Merton’s theory of cumulative advantage in science (Matthew Effect), several empirical studies have tried to measure its presence at the level of papers, individual researchers, institutions, or countries. However, ...
  • Interdisciplinarité 

    Prud’homme, Julien; Larivière, Vincent; Gingras, Yves (Les presses de l’Université de Montréal, 2015-05)
  • Measuring interdisciplinarity 

    Larivière, Vincent; Gingras, Yves (2014)
  • Modeling a century of citation distributions 

    Wallace, Matthew L.; Larivière, Vincent; Gingras, Yves (Elsevier, 2009-05-06)
    The prevalence of uncited papers or of highly cited papers, with respect to the bulk of publications, provides important clues as to the dynamics of scientific research. Using 25 million papers and 600 million references from the Web of Science over ...
  • On the prevalence and scientific impact of duplicate publications in different scientific fields (1980‐2007) 

    Larivière, Vincent; Gingras, Yves (Emerald, 2010-03-09)
    The issue of duplicate publications has received a lot of attention in the medical literature, but much less in the information science community. This paper aims at analyzing the prevalence and scientific impact of duplicate publications across all ...
  • On the relationship between interdisciplinarity and scientific impact 

    Larivière, Vincent; Gingras, Yves (Association for information science and technology, 2009-12-09)
    This article analyzes the effect of interdisciplinarity on the scientific impact of individual articles. Using all the articles published in Web of Science in 2000, we define the degree of interdisciplinarity of a given article as the percentage of its ...
  • Self-selected or mandated, open access increases citation impact for higher quality research 

    Gargouri, Yassine; Hajjem, Chawki; Larivière, Vincent; Gingras, Yves; Carr, Les; Brody, Tim; Harnad, Stevan (Public library of science, 2010-10-18)
    Background: Articles whose authors have supplemented subscription-based access to the publisher’s version by selfarchiving their own final draft to make it accessible free for all on the web (‘‘Open Access’’, OA) are cited significantly more than ...
  • A small world of citations? : the influence of collaboration networks on citation practices 

    Wallace, Matthew L.; Larivière, Vincent; Gingras, Yves (Public library of science, 2012-03-07)
    This paper examines the proximity of authors to those they cite using degrees of separation in a co-author network, essentially using collaboration networks to expand on the notion of self-citations. While the proportion of direct selfcitations ...
  • Team size matters : collaboration and scientific impact since 1900 

    Larivière, Vincent; Gingras, Yves; Sugimoto, Cassidy R.; Tsou, Andrew (Association for information science and technology, 2014-11-06)
    This paper provides the first historical analysis of the relationship between collaboration and scientific impact, using three indicators of collaboration (number of authors, number of addresses, and number of countries) and including articles published ...
  • The weakening relationship between the impact factor and papers' citations in the digital age 

    Lozano, George A.; Larivière, Vincent; Gingras, Yves (Wiley, 2012-10-08)
    Historically, papers have been physically bound to the journal in which they were published but in the electronic age papers are available individually, no longer tied to their respective journals. Hence, papers now can be read and cited based on ...
  • Which scientific elites? : on the concentration of research funds, publications and citations
