Lorca según Cernuda: sobre «A un poeta muerto (F. G. L.)»
Get PDFAn analysis of Luis Cernuda’s “A un poeta muerto (F. G. L.)” that does not disregard close reading while at the same time situates the text in its context discloses that the poet elaborated a picture of Lorca by picking some traits and discarding others; that this careful selection has a fuller meaning when watched against the background of Cernuda’s disputes with Dámaso Alonso and other friends of Lorca’s; that in that portrayal of Lorca there is a mirror of Cernuda himself; and that this mirror plays a revealing part and contains a personal statement within the literary and political struggle of 1937 Valencia, where the poem was written and published first.Un análisis de «A un poeta muerto (F. G. L.)» que sin renunciar a la lectura atenta preste atención al contexto permite advertir que Cernuda elabora allí una determinada imagen de Lorca mediante la selección de unos rasgos; que esta selección posee un sentido muy determinado dentro de la disputa con Dámaso Alonso y otros amigos de Lorca; que en ese Lorca, el Lorca según Cernuda, habría un espejo del propio Cernuda; y que esa imagen cumple una función y contiene un pronunciamiento dentro de las polémicas literarias y políticas de la Valencia de 1937 en que se escribió y publicó

Cepa de Sinorhizobium meliloti halotolerante confiere tolerancia a la salinidad a Medicago sativa L.
Get PDFObjective. To comprehensively evaluate the effect of salinity on CW 660 Medicago sativa L. plants subjected to two treatments: nitrogen fertilization and inoculation with a halotolerant strain of Sinorhizobium meliloti. Materials and methods. M. sativa L. plants were di-vided into two groups: fertilized with nitrogen but not inoculated with S. meliloti (FP) and inoculated with S. meliloti but not fertilized (IP). Salt stress was induced with Hoagland’s solution and NaCl (50, 100, and 200 mM) for FP, the same solution with limited nitrogen for IP. Response variables length (L), fresh weight (FW), and dry weight (DW) of roots and aerial parts, photosynthetic pigments (chlo-rophylls a and b and carotenoids), and proline concentration were measured after four weeks. Results. Generalized additive models (GAM) were used to evaluate the effect of salinity and inoculation on the response variables. The ino-culated plants showed significant improvements in aerial and radical length, and chlorophylls a and b under salinity stress compared to the fertilized plants FP. Proline concentration was decreased in IP. Nodulation decreased due to salt stress, but inoculation promoted active no-dules. Conclusion. Inoculation with halotole-rant S. meliloti improved salt stress resistance and growth in plant.Objetivo. Evaluar de manera integral el efecto de la salinidad en plantas de la variedad CW 660 de Medicago sativa L., sometidas a dos tratamientos: fertilización con nitrógeno e inoculación con una cepa halotolerante de Sinorhizobium meliloti. Materiales y métodos. Las plantas de M. sativa L. se dividieron en dos grupos: fertilizadas con nitrógeno, pero no inoculadas con S. meliloti (PF) e inoculadas con S. meliloti pero sin fertilización (PI). El estrés salino se indujo con solución de Hoagland y NaCl (50, 100 y 200 mM) para PF, misma solución con nitrógeno limitado para PI. Las variables repuestas evaluadas fueron longitud (L), peso fresco (PF) y peso seco (PS) de raíces y partes aéreas, pigmentos fotosintéticos (clorofilas a, b y carotenoides) y concentración de prolina tras cuatro semanas de tratamiento. Resultados. Mediante modelos aditivos generalizados (GAM, por sus siglas en inglés), se evaluó el efecto de salinidad e inoculación sobre las variables repuestas. Las PI mostraron mejoras significativas en la longitud aérea y radical, y en las clorofilas a y b bajo estrés salino, en comparación con PF. La concentración de prolina bajó en PI. La nodulación disminuyó debido al estrés salino, pero la inoculación promovió nódulos activos. Conclusión. La inoculación con S. meliloti halotolerante mejoró la resistencia al estrés salino, impulsando el crecimiento de las plantas.Fil: Gonzalez, Evelyn Ailen.

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
