Biotecnología agroalimentaria : más allá de la casuística
Full text linkFil: Ibarra, Andoni. Universidad del País Vasco; España.Fil: Rodríguez, Hannot. Universidad del País Vasco; España.El desarrollo de la biotecnología agroalimentaria está siendo blanco de una fuerte controversia científico-social en Europa. Por una parte, esta controversia se ha fijado desde los ámbitos institucional y académico dominantes a partir, sobre todo, de las cuestiones relacionadas con el consumo humano y su seguridad, dejando de lado otros aspectos. Por otro lado, la conceptuación de la aceptabilidad de la biotecnología agroalimentaria viene determinada por un discurso casuístico, que establece la viabilidad de este desarrollo biotecnológico concreto a partir del análisis de sus distintas aplicaciones. En consecuencia, relevantes aspectos constituyentes de ese desarrollo, indispensables para su comprensión, permanecen inmunes al análisis. Evaluamos los efectos de esta situación a partir de la regulación española de los riesgos de la biotecnología agroalimentaria
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
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
La confianza pública en las instituciones reguladoras del riesgo: tres modelos de confianza para tres desafíos del análisis del riesgo
Full text linkSocial studies of risk have dignified the social resistance to scientific-technological progress by means of their analyses about trust relations between the public and institutions in charge of safety. These analyses have contributed remarkably to dismantle the idea that the social resistance to industry-based science and technology development is a consequence of an irrational public attitude toward the real risks of that development. The arguments used to this end can be classified in three models for the understanding of trust relations: competence model, cultural model and relational model. Each of these models refers to an essential challenge the institutional risk analysis has to cope with in order to be seen as legitimate. Respectively: epistemological challenge, axiological challenge and reflexive challenge. These challenges will be presented in the light of the European regulation of genetically modified organisms.Los estudios sociales del riesgo han dignificado la resistencia social al progreso científico-tecnológico por medio del análisis acerca de las relaciones de confianza entre el público y las instituciones expertas encargadas de la seguridad. Estos análisis han contribuido notablemente a desmontar la idea de que la resistencia social al desarrollo de la ciencia y la tecnología industrialmente guiado es consecuencia de una actitud irracional del público hacia los riesgos verdaderos de ese desarrollo. Los argumentos utilizados para ello pueden clasificarse en tres modelos para la comprensión de las relaciones de confianza: modelo competencial, modelo cultural y modelo relacional. Cada uno de estos modelos apela a un desafío básico al que debe enfrentarse el análisis institucional del riesgo para verse legitimado. Respectivamente: desafío epistemológico, desafío axiológico y desafío reflexivo. Estos desafíos se presentarán a la luz de la regulación europea de los organismos modificados genéticamente
