    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

    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

    Cronosecuencia de regeneración natural en bosques remanentes y bosques secundarios sucesionales después de la extracción de oro en la selva amazónica de Madre de Dios, Perú

    Gold extraction via small scale mining in the Amazon rainforest of Peru has become one of the greatest threats to deforestation and land degradation in the Amazon, especially in the Madre de Dios region which is one of the last biggest remnants of continuous tropical rainforest in the world. Restoration of these degraded ecosystems have become a priority in the last decade but without concrete actions, however, few research has been conducted in response to these restoration activities nor natural regeneration. The significance of this research was to 1) To Analyze how gold mining affects forest structure, species richness and diversity in the Amazon Rainforest of Madre de Dios, Peru. 2) To assess variation on diversity levels in secondary successional forest compared to that found in primary forest 3) to identify variations in the gold extraction methods reported in the region and how it affect forest recovery 4) to outstand the importance of remnant forest, if present, in nearby areas and finally 5) explore the existence of other factors that may prevent forest recovery after sever disturbances in four active gold-mining sites in Madre de Dios- Peru (Paolita-PA; Santa Rita-ST; San Jacinto-SJ and Aide-A. Sites were chosen depending on its management and the proximity to nearby remnant forest. Floristic composition of natural regeneration following abandonment of mining activities was studied by establishing a total of 21 plots (20x50m each) from which 8 plots were considered as primary-remnant forest and 13 plots were secondary growth forest spanning a period of 2 to 16 years of growth A total of 1404 individuals were described, representing 182 species scattered in 50 families from which only 21 species represented 50% of the total species found during the survey. To analyze biodiversity and similarity composition, Shannon and Jaccard indexes were used, respectively from which it was found that, the reduction of diversity within stages of succession confirms, as for this thesis, that diversity does not increases with time but instead, it decreases as the plot ages due additional factors over plots with more than five years after the cease of mining. As for variations in method of gold extraction, results did not shown significant variations in forest development that could be related to method of gold extraction but instead, climate might be playing an important role in forest development.Este estudio se enfocó en la composición florística de la regeneración natural tras el abandono de las actividades mineras estableciendo un total de 21 parcelas (20x50m); 8 parcelas en bosque remanente primario y las restantes en crecimiento secundario con un período de 2 a 16 años de crecimiento. Se describieron 1404 individuos, representando 182 especies en 50 familias, de donde 21 especies representaron el 50% del total de especies encontradas durante la encuesta. Para analizar la biodiversidad y la similitud se utilizaron los índices de Shannon y Jaccard, respectivamente, de donde se encontró que la reducción de la diversidad dentro de las etapas de sucesión confirma que la diversidad no aumenta con el tiempo, sino que disminuye a medida que avanza el tiempo. La parcela envejece debido a factores adicionales sobre parcelas con más de cinco años después del cese de la explotación. En cuanto a las variaciones en el método de extracción de oro, los resultados no mostraron variaciones significativas en el desarrollo forestal que pudieran estar relacionadas con el método de extracción de oro, sino que el clima podría estar desempeñando un papel importante en el desarrollo forestal.Japón.

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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.
