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
México y la extradición de nacionales
No full textLos argumentos en contra de la extradición defienden la visión de que los nacionales estarán en desventaja en tribunales extranjeros o que otros sistemas jurídicos no aseguran que exista un juicio justo. Los países del common law están más dispuestos a extraditar a sus nacionales, mientras que los países del civil law sólo admitirán la extradición de sus nacionales en circunstancias excepcionales. Desde 1995 la política mexicana ha sido profundamente revisada, y el principio de aut dedere aut judicare en el tratado en vigor ha favorecido el castigo de presuntos criminales aunque no sean extraditados. La Suprema Corte de Justicia de México ha fallado para resolver una contradicción entre tribunales de menor jerarquía respecto de la facultad del Ejecutivo de extraditar a nacionales mexicanos. La solución, que el autor explica, es que el Código Penal mexicano no impide al Ejecutivo extraditar nacionales, sino que se aplica el artículo 9.1 del tratado en vigor
Convention on the Legal Status of the Caspian Sea
Full text linkMaestro en administración pública por el Instituto Tecnológico y de Estudios Superiores de Monterrey, licenciado en Derecho por la Universidad Iberoamericana. Estudiante de doctorado en Khazar University.El 12 de agosto de 2018, el Mar Caspio —la cuenca endorreica más grande del mundo—recibió por primera vez en la historia un estatuto jurídico. En esa fecha, después de más de veinticinco años de negociación y cinco cumbres presidenciales, Azerbaiyán, Irán, Kazakhstán, Rusia y Turkmenistán (los “5-Caspio”), suscribieron en Aktau, Kazakhstán, la Convención sobre el Estatuto Jurídico del Mar Caspio (“la Convención”). El Mar Caspio es un cuerpo de agua que conecta a Asia con Europa y que igualmente les divide. La Convención incorpora al derecho internacional (regional), prácticas y principios de los cinco Estados ribereños del Mar Caspio adoptados antes y después de la extinción de la Unión de Repúblicas Socialistas Soviéticas (URSS)

A Hinge in Eurasia: Regional infrastructure and geopolitical changes.
Full text linkABSTRACT
While Asia and Europe lie in the same landmass, they have always been considered two separate and distinct continents. The land route between East (China) and West (Europe) must traverse the Caspian Sea or its northern (Russia) or southern (Iran) shores —with heightened attention due to international sanctions and the Russian invasiton of Ukraine. While geography dominates one’s environment, it is one’s will which molds destiny. Geography without infrastructute is a dot on a map. A door lies between East and West: the Caspian Sea, with the Caucasus as its hinge, and infrastructure as its lubricant
