    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

    Introdução: A Síndrome da Imunodeficiência Adquirida ocorre devido presença do vírus HIV no organismo afetando o sistema imunológico, podendo deteriorá-lo, permitindo a manifestação de infecções oportunistas. Estas infecções podem acometer o Sistema Auditivo Periférico trazendo prejuízo à audição dos indivíduos infectados. A literatura aponta a avaliação da Audiometria em Altas Frequências como um preditor importante para as alterações deste sistema. Objetivo: Caracterizar as manifestações audiológicas em indivíduos com HIV / AIDS submetidos e não submetidos à terapia antirretroviral. Método: A avaliação audiológica foi realizada em 28 indivíduos do GPI com HIV/AIDS, submetidos à terapia antirretroviral; 24 indivíduos do GPII com HIV/AIDS, não submetidos à terapia antirretroviral e 45 indivíduos saudáveis do GC. Os exames audiológicos que compuseram esta pesquisa foram: Audiometria Tonal Convencional, Logoaudiometria, Audiometria em Altas Frequências, Medidas de Imitância Acústica. Resultado: Para as medidas de Imitância Acústica não houve diferença estatisticamente significante para os resultados obtidos entre os grupos, tanto para a Timpanometria, como para os Reflexos Acústicos. Observou-se também, que para os três grupos, a proporção de resultados normais para a Timpanometria é maior, enquanto para os Reflexos Acústicos, a maior proporção foi de resultados alterados. Os grupos GPI e GPII, compostos por indivíduos com HIV/AIDS apresentam alterações tanto na avaliação audiológica convencional, como em altas frequências. Em relação à Audiometria Tonal Convencional, na comparação entre os grupos, observou-se limiares auditivos mais elevados nas frequências de 250 Hz, 1000 Hz, 2000 Hz, 4000 Hz, 6000 Hz e 8000 Hz para os indivíduos com HIV/AIDS. No que diz respeito à Audiometria em Altas Frequências, os resultados obtidos demonstraram, também, limiares auditivos mais elevados em indivíduos com HIV/AIDS nas frequências de 10 KHz, 11,2 KHz, 12,5 KHz, 14KHz, 18 kHz e 20 KHz. Conclusão: Para as Medidas de Imitância Acústica, não foi observada diferença entre os três grupos. Indivíduos com HIV/AIDS apresentam mais alteração na Audiometria Tonal Convencional e na Audiometria em Altas Frequências quando comparados a indivíduos saudáveis, sugerindo, comprometimento do sistema auditivo periférico. Não houve diferença significativa entre indivíduos com HIV/AIDS submetidos e não submetidos à terapia antirretroviralIntroduction: Acquired Immune Deficiency Syndrome occurs as a result of the presence of the HIV virus in the body affecting the immunological system, potentially making it deteriorate, allowing the manifestation of opportunistic infections. These infections can attack the peripheral hearing system causing hearing damage to the infected individuals. Literature indicates High Frequency Audiometry as an important pointer to the alterations of the peripheral hearing system. Objective: To characterize the audiological manifestations in individuals with HIV/AIDS submitted and not submitted to antiretroviral therapy. Method: The audiological evaluation was carried out in 28 individuals of GPI with HIV/AIDS submitted to antiretroviral therapy; 24 individuals of GPII with HIV/AIDS not submitted to the antiretroviral therapy and 45 healthy individuals of GC. The audiological tests that make up this survey were: Conventional Tonal Audiometry, Speech Audiometry, High Frequency Audiometry and Acoustic Immitance Measures. Result: In the measurement of Acoustic Immitance, there was no statistically significant difference in the results obtained amongst the groups, for Tympanometry Test and for Acoustic Reflexes. It was also observed that for the three groups, the percentage of normal results for Tympanometry Test was higher, whilst for Acoustic Reflexes the higher percentage was of altered results.The groups GPI and GPII, formed by individuals with HIV/AIDS, presented alterations in the conventional audiological evaluation as well as in the high frequency one. With regards to the Conventional Tonal Audiometry, in the comparison amongst the groups, it showed higher audiometrics thresholds in frequencies of 250 Hz, 1000 Hz, 2000 Hz, 4000 Hz, 6000 Hz and 8000 Hz for individuals with HIV/AIDS. Regarding High Frequency Audiometry, the results also showed higher audiometrics thresholds in individuals with HIV/AIDS in frequencies of 10 KHz, 11,2 KHz, 12,5 KHz, 14KHz, 18 kHz and 20 KHz. Conclusion: There was no difference in the Measurements of Acoustic Immitance observed amongst the three groups Individuals with HIV/AIDS present more alterations in Conventional Tonal Audiometry and in High Frequency Audiometry when compared to healthy individuals which indicates a compromise on the peripheral hearing system. There was no significant difference between individuals with HIV/AIDS submitted and not submitted to antiretroviral therap

    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

    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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
