Instituciones y grupos de interés: el abasto de carne en la ciudad de México, c. 1850-1967
Full text linkEste artículo analiza el sistema de abasto de carne de la ciudad de México desde la década de 1850 hasta 1967. Durante este periodo, mientras algunos centros urbanos del continente americano reemplazaron sus métodos tradicionales de aprovisionamiento -el sistema de rastros- con compañías empacadoras, la ciudad de México siguió dependiendo del monopolio municipal para proveer de carne a las masas. Este estudio se centra en el rol que jugaron en este proceso los ganaderos, proveedores de ganado (introductores) y trabajadores del rastro, junto con las autoridades de la ciudad. Muestra cómo estos actores evolucionaron adaptándose a cualquier autoridad en el poder sin importar la ideología y cómo grupos de interés, introductores, trabajadores y ganaderos no sólo proporcionaron un servicio a los habitantes de la ciudad, sino que, con diferentes grados de influencia, también proveyeron un importante apoyo político para los gobiernos. Por su parte, y en nombre del orden público, las autoridades de la ciudad protegieron esas asociaciones como forma de gestionar los suministros. Esta relación de beneficio mutuo les permitió a ambos (grupos de interés y autoridades) resistirse a los conglomerados de empacadoras hasta bien entrado el siglo XX. Este trabajo resalta que, aunque en ocasiones estos arreglos facilitaron el suministro de carne, en otras no permitieron que las proteínas animales llegaran hasta los trabajadores pobres - uno de los objetivos principales del México posrevolucionario.This paper examines Mexico City's meat supply system from the 1850s to 1967. During this period, whereas some urban centers in the Americas replaced traditional provisioning methods - abattoir system - with meatpacking companies, Mexico City continued to rely on the municipal monopoly to provide meat for the masses. This study focuses on the role that ranchers, cattle purveyors (introductores), and slaughterhouse (rastro) workers, alongside city officials, played in this process. It shows how these actors evolved accommodating to any authority in power, regardless of ideology. As interest groups, introductores, workers, and ranchers not only delivered a service to city dwellers but with varying degrees of influence, they also provided essential political support to governments. For their part, city officials protected these associations as a means of managing supplies and in the name of public order. Such a mutually beneficial relationship allowed both (interest groups and the municipality) to resist meatpacking conglomerates well into the twentieth century. The work underscores that although at occasions these arrangements facilitated meat provision, in others, they hindered the extension of animal proteins to the working poor - one of the main goals of post-revolutionary Mexico.Fil: Lopes, Maria-Aparecida.

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
