    MeSH term explosion and author rank improve expert recommendations

    No full text
    Information overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

    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

    "Closing the R&D Gap, Evaluating the Sources of R&D Spending"

    No full text
    Both spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    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

    Uma voz que clama no D(d)esterro: (fixação do texto poético inédito de Juvêncio de Araújo Figueredo)

    Tese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaUm voz que clama no D(d)esterro é o resgate, com vistas a publicação, da obra poética inédita de Juvêncio de Araújo Figuerêdo (Florianópolis, 1864-4927). O trabalho está estruturado em três partes: A primeira apresenta as idéias introdutórias, que falam do poeta e sua vida, de vozes dele e sobre ele, do seu fazer literário, da fundamentação teórica que dá suporte à seleção do material (Filologia e Edótica); sua transcrição (Diplomática e Crítica Genética), sua atualização (Gramática Histórica), e a preparação do volume para edição (Bibliologia). Esses elementos são buscados em Segismundo Spina, Cecília Almeida Salles, Phillipe Willemart, Ismael de Lima Coutinho e Antônio Houaiss. A segunda parte contém a transcrição do texto e sua atualização. A terceira parte contém o capítulo conclusivo, a bibliografia, o glossário e os anexos, sugerindo também o volume pronto para. Cada poema é comparado com o conteúdo do livro Poesias e Madrigais, referencial considerado para se afirmar se o texto é inédito ou não. A transcrição orienta-se pelo catálogo de documentos fornecidos pela Biblioteca Nacional do Rio de Janeiro. Cada poema é transcrito inclusive nas suas versões, quando houver. Terá à direita observações segeridas pela Crítica Genética (sinais adotados). No rodapé é feito comentário específico. Quando esse comentário for muito extenso, será feito em página própria, seguinte. O texto resgatado integralmente compõe o pretendido volume de poemas a ser publicado. O texto com algumas retrições é reservado para posterior complementação com a colaboração dos familiares do poeta, e pode compor o referido volume. O texto altamente problemático, é refutado. O material (microfilmes e xerocópias dos originais) está acondicionado em caixas. Quando se tratar de poemas muito extenso, será acondicionado em cilindros, para proporcionar melhor proteção ao material, pois não haverá dobraduras. Esses continentes serão devidamente identificado. O material será doado à Academia Catarinense de Letras

    The R&D Tax Incentives

    No full text
    This article sets out some background information and reflections of the author on the R&D tax incentive schemes included in the Common Corporate Tax Base (CCTB) Proposal. In particular the author analyzes the stimulus to private R&D through ad hoc tax incentives included in the CCTB Proposal and dives into the actual provisions included in the Proposal highlighting the most relevant issues connected with their design and interpretation. Moreover, the author explores the interaction between the CCTB Proposal and the granting by Member States of domestic R&D tax incentives
