Economic efficiency analysis of the Spanish olive industry
No full text[ES] El trabajo aborda una aproximación al análisis de la eficiencia económica de la industria oleícola española y los factores que pueden influir en ella. El análisis se ha realizado aplicando la metodología no paramétrica del Análisis Envolvente de Datos (DEA). La muestra está compuesta por un total de 429 empresas oleícolas que aparecen en la base de datos SABI en el año 2021. Los inputs utilizados han sido: Gastos en Personal, Aprovisionamientos e Inmovilizado, mientras que como output único se ha considerado las Ventas. El posterior recurso a pruebas estadísticas no paramétricas muestra diferencias significativas únicamente por tamaño empresarial.

The analysis has been carried out applying the non-parametric methodology of Data Envelopment Analysis (DEA). The sample is made of a total of 429 olive oil companies that appear in the SABI database in 2021. The inputs used have been: Staff costs, Supplies and Fixed Assets, while Sales have been considered as the only output. The later non-parametric statistical tests has shown significant differences only by company size.

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
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
Valoración de los bienes y servicios que presta la agricultura. Aplicación al sistema agrario de la huerta de valencia
No full textCon esta investigación hemos pretendido contribuir al reconocimiento de la
multifuncionalidad de la agricultura, defendiendo una actividad que desempeña una
función económica, a la vez que otras funciones relativas la protección del medio ambiente
y del paisaje, a la conservación del patrimonio cultural, a la mejora de los aspectos de
equilibrio social, así como la posibilidad de proveer servicios recreativos. Estas funciones
generan bienes y servicios que no tienen mercado, pero para los que existe una demanda
social.
De acuerdo con los objetivos planteados para este trabajo de investigación se ha
desarrollado una aproximación descriptiva de la multifuncionalidad de la agricultura, como
marco teórico para el desarrollo posterior de análisis de la demanda de los bienes y
servicios que pueden proveer los sistemas agrarios, y las funciones que pueden
desempeñar, así como para la determinación de una función de utilidad, que guíe la
definición de las políticas de intervención. El esquema se ha aplicado al caso concreto de la
Huerta de Valencia, que es un sistema agrario de gran riqueza y con gran variedad de
recursos, sobre el que hay abierto un debate político-institucional para definir un régimen
de protección. Se ha podido establecer las funciones y los bienes y servicios que provee
este espacio agrario, base del análisis de la demanda social de estos bienes y servicios y de
la determinación de una función de utilidad.
La estimación de las preferencias sociales por las funciones que desarrolla la
Huerta, se ha realizado mediante metodologías de análisis multicriterio, y más
concretamente el Analytic Hierarchy Process (AHP) para valorar las prioridades sociales e
interpretarlas en términos de utilidad, y de demanda social, para integrarlas en las
decisiones de políticas encaminadas a la promoción de aquellas funciones de los sistemas
agrarios con los que se maximizaría la utilidad del mismo.Marqués Pérez, I. (2013). Valoración de los bienes y servicios que presta la agricultura.
