    Effective spectral systems relating Serre and Eilenberg–Moore spectral sequences

    Get PDF
    Working in a simplicial and constructive context, a new spectral system is defined that relates Serre and Eilenberg-Moore spectral sequences associated to a principal simplicial fibration. The two Eilenberg-Moore spectral sequences (the one where the homology of the fiber is the output, and the other where the homology of the base is computed) are used in our construction. Explicit computer programs are developed, enhancing the Kenzo computer algebra tool to implement that spectral system.</p

    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

    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

Centro de Investigaciones Interdisciplinarias en Ciencias y Humanidades; México.El concepto marxiano de fetichismo de la mercancía es susceptible de aplicación en biología evolutiva para revelar muchas imprecisiones contenidas en las concepciones neodarwinistas y parte de su carácter ideológico. Postulo que el Dogma Central de la Biología Molecular es una expresión de la fetichización de procesos complejos que requieren la concurrencia de múltiples variables y entidades, que no siempre pueden ser explicados a partir de la presencia de los ácidos nucleicos. El presente trabajo lleva tres niveles de análisis: por una parte en el método dialéctico hegeliano-marxista, por otra en las tesis de Karl Marx, e Ivan Rubin acerca del fetichismo de la mercancía y finalmente en la obra de evolucionistas como S. Oyama, Richard Lewontin y Richard Levins. Pongo especial énfasis en la Teoría de Sistemas en Desarrollo, postulada por Oyama, afirmando que es una innovadora concepción que devela fetichismos y mistificaciones del neodarwinismo.The Marxian concept of Commodity Fetishism can be applied on evolutionary biology to expose inaccuracies of NeoDarwinist conceptions and their ideological nature. I postulate that the Central Dogma of Molecular Biology is an expression of the fetishization of complex processes that require the concurrence of multiple variables and entities. The present work has 3 levels of analysis: first, the Hegelian-Marxist dialectical method; second, the Karl Marx and Ivan Rubin thesis on fetishism of commodities; and finally, the work of evolutionists such as Susan Oyama, Richard Lewontin, and Richard Levins. I argue that the Developmental Systems Theory, proposed by Oyama, is an innovative conception that reveals fetishisms and mystifications of Neo-Darwinism

    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    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

    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
