Importantes Frutas Tropicales
Get PDFLa ciencia de la pomología tropical, aunque todavía está de recibir toda la atención que se merece, ha avanzado mucho desde principios del siglo actual, especialmente en lo que se refiere a algunos de sus aspectos más fundamentales, y de los cuales se tratará brevemente en este estudio
El Problema de la Variedad en la Horticultura Tropical
Get PDFLa pomología tropical, carece del respaldo extenso de investigación técnica y desarrollo que caracteriza a la horticultura en regiones más septentrionales. Los que trabajamos con frutas tropicales tenemos que satisfacernos con material que es, hablando en términos comparativos, todavía primitivo. Además, estamos empeñados en explorar nuevas regiones en sentido hortícola. Nuestra tarea es determinar qué clase de frutas se pueden, cultivar en estas regiones y cuál es la mejor forma de hacerlo
Cultivo de la Quina [Cínchona] en Guatemala
Get PDFA mediados del siglo pasado, el rápido incremento que tomó la destrucción de los bosques de quina (Cínchona) de los Andes y el aumento del valor de la quinina para el tratamiento de la malaria, dió por resultado la introducción del cultivo de Cínchona en los dominios tropicales de la Gran Bretaña y Holanda. Respecto a estos cultivos el mundo recuerda con gratitud a hombres como Weddell y Markham, quienes estudiaron estos árboles en sus hogares nativos, habiendo insistido en la iniciación de tal empresa. El interés que promovió el cultivo de Cínchona por los años de 1850 y 1860 en adelante, parece que repercutió en muchas regiones, siendo Guatemala una de ellas
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
