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
Agua : el gobierno incumple con la Constitución
Get PDFProbablemente el asunto más evidente e importante de esa “agenda olvidada” del régimen es la aprobación de la Ley Orgánica de Recursos Hídricos, Usos y Aprovechamiento del Agua, que de acuerdo a la Constitución de Montecristi, debió haber sido aprobada un año después de su entrada en vigencia. El presidente Correa declaró a esa ley “no prioritaria” para la propuesta política de la revolución ciudadana, por lo que se podía gobernar sin ella. En ese sentido, efectivamente se ha gobernado con una ley vigente desde 1972, misma que fue reformada de modo inconstitucional mediante una codificación realizada en abril de 2004. Esa ley posibilitó el acaparamiento de agua en pocas manos. Por lo demás, la vigencia de esa norma de carácter neoliberal es algo contrario a los mandatos de la Constitución de 2008
Derechos al agua en comunidades campesinas e indígenas El caso de Ecuador
No full textWater management in Ecuador has significant experience from prehistoric times to the present, where scenarios such as the recognition of ancestral conservation strategies, struggles for access and control from sectors of power, legal approaches that in the new Constitution confer the right and order of priority to water, and others. It is necessary to review compliance with the right to water in peasant and indigenous communities, which has historically been restricted, causing situations of water injustice in the communities that live in the territories where the water is born. Ecuador's legal system grants rights to nature and water, but it must also ensure the right of the population to enjoy water as a fundamental right, in a context of respect and appreciation of worldviews for their care. This article begins with a historical perspective in which changes and loss of rights are observed in the neoliberal phase, to give way to the formal recovery of those rights linked with a legal pluralism, which today leaves new challenges for the whole social and nationalities and indigenous peoples in particular.La gestión del agua en el Ecuador cuenta con una importante experiencia desde tiempos prehistóricos hasta tiempos actuales, donde destacan escenarios como el reconocimiento de estrategias ancestrales de conservación, pugnas por el acceso y control desde sectores de poder, abordajes legales que en la nueva Constitución le confiere derecho y orden de prelación al agua. A su vez, es necesaria la revisión del cumplimiento del derecho al agua en las comunidades campesinas e indígenas, que históricamente ha sido restringido, provocando situaciones de injusticia hídrica en las comunidades que viven en los territorios donde nace el agua. El ordenamiento jurídico del Ecuador concede derechos a la naturaleza y al agua, pero también debe velar por el derecho de la población al disfrute del agua como un derecho fundamental, en contexto de respeto y valoración de las cosmovisiones para su cuidado. En este artículo se inicia con una perspectiva histórica en la que se observa cambios y perdida de derechos en la fase neoliberal, para dar paso a la recuperación formal de esos derechos en medio de un pluralismo jurídico, que hoy deja planteados nuevos retos para el conjunto social y las nacionalidades y pueblos indígenas en particular

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
