Intercambios Oceánicos–México. Trazando redes de información global en repositorios de periódicos históricos, 1840-1914
Get PDFOceanic Exchanges was configured as an international project composed of researchers from six countries, including Mexico. The national team was coordinated by the Hemeroteca Nacional de México to work on digital tools that would allow -as the name of the project indicates- to trace global information networks in historical newspapers repositories between 1840 and 1914. The text analyzes the news searches made in various case studies in order to present the different methodologies used and develop information flows, news circulation and origin of informative texts, as well as the use and reuse of news. In general, is the aim to offer an innovative approach to work out digital repositories from various countries.

La Intendencia en Venezuela. Conflictos y luchas por la reorganización económica de la Capitanía, 1777-1788
No full textEl escenario bélico entre las potencias europeas de mediados del siglo XVIII impulsó en territorios americanos una apresurada aplicación de reformas al interior del sistema colonial español fundamentadas en la ampliación administrativa, la transformación de la estructura económica, así como, la adopción de polémicos cambios sociales. En Venezuela la implementación de estas reformas fue de lento alcance, pero de progresiva mejora, pues pasó de ser una provincia a convertirse en una Capitanía General independiente de Santa Fe y Santo Domingo. El propósito de los primeros intendentes no solo pretendió satisfacer intereses económicos de la monarquía, sino también, alentar la participación de élites criollas en sectores comerciales con fuertes intereses por la producción agrícola. Ser eje en el Caribe permitió ejecutar una política distinta de extracción de recursos, pues ante la escasa comprobación de riquezas metales, se contaba con una fuerza formidable al existir tierra fértil y una considerable población negra o descendiente de ella. No obstante, ante el florecimiento económico surgió el que fuera considerado el mayor problema local, el contrabando, tan difícil de vigilar como la misma amplia costa venezolana. El presente texto se interesa por abordar las apuestas económicas de la Intendencia, el impulso comercial a los frutos de la tierra, así como, el enfrentamiento político entre las autoridades locales y provinciales. Aunado a ello, del combate que desde la intendencia se ofreció para derrocar el contrabando en medio de un contexto de guerras con potencias extranjeras y de luchas sociales por la exigencia de mejor posicionamiento social.The war scenario between the European powers in the mid-eighteenth century encou-raged the application of reforms in the American territories based on administrative expansion, the transformation of the economic structure, as well as the adoption of controversial social changes. In Venezuela, the reforms of the monarchy admitted two fundamental changes: going from being a province to becoming a Captaincy General independent of Santa Fe and Santo Domingo and establishing the regime of the Inten-dancy. The first intendants not only sought to satisfy the economic interests of the monarchy, but also to encourage the participation of creole elites in commercial sectors with strong interests in agricultural production. Venezuela carried out a different policy of resource extraction, since it had a formidable potential due to the existence of fertile land and a considerable black population or descendants of them. This text is interested in addressing the economic bets of the first two intendants, the commercial impulse to the fruits of the land, as well as the political confrontation between local and provincial authorities derived from economic control. In addition, there is the application of regu-lations that are counterproductive to the economy in the midst of a context of wars with foreign powers and social struggles for the demand for better social positioning

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
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
