Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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
Full text linkWe 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
Crisis y decadencia: el virreinato del Perú en el siglo XVII
Full text linkEn coedición con el Banco Central de Reserva del PerúEl siglo XVII fue una centuria de cambios y, por lo mismo, de crisis para la economía del virreinato del Perú. La minería dejaba de ser el único motor de la producción y el intercambio; comenzaba a compartir su papel con otros sectores, menos vinculados al mercado exterior y más conectados con las necesidades locales. En este contexto, sobrevino un programa de reforma fiscal desde Madrid, que se propuso aumentar la carga tributaria que pesaba sobre la colonia. La mitad del siglo XVII fue el escenario temporal de la batalla que libraron las autoridades metropolitanas, las virreinales y los empresarios coloniales por imponer los nuevos tributos, los primeros, y por esquivarlos, los últimos. Crisis y decadencia. El virreinato del Perú en el siglo XVII, da cuenta de esa historia; al hacerlo ilumina el proceso económico que vivía el Perú un siglo después de terminada la conquista española y ofrece datos valiosos sobre la producción, el comercio y la recaudación tributaria
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
Espanhóis, andinos e o estado colonial inicial no Peru
No full textPolitical instability and factionalism preceded the establishment of Peru's colonial state, so righy after the Spanish invasion the state is fragile and almost unexistent. Vicerroy Toledo organized administrative, fiscal and forced labor system reforms attempting to create an all-powerful colonial state. However, the state power declined because of the failure of maintaining equilibrium and stability. both in production and in population. Corruption, inefficiency, and cooptationamong the members of the colonial elite contributed to erode the very foundations of the colonial state Al establecimiento del estado colonial precedieron en el Perú la inestabilidad política y el fraccionalismo, de manera tal que a posteriori de la invasión española, el estado es frágil y casi inexistente. El virrey Toledo es quien realiza una profunda reforma administrativa, fiscal y laboral tendiente a la creación de un poderoso estado colonial. Sin embargo ese intento fracasará puesto que su equilibrio giraba en torno a la estabilidad demográfica, de la producción agrícola y el mantenimiento de los pueblos de indios. La corrupción, la ineficiencia y la cooptación entre los miembros de la élite colonial contribuyeron a erosionar los cimientos del estado colonial peruano.O estabelecimento do Estado colonial no Peru foi precedido por instabilidade política e faccionalismo, de tal forma que, após a invasão espanhola, o Estado se tornou frágil e quase inexistente.
