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
El sector agroalimentario marroquí y la liberalización del comercio
Full text linkLos acuerdos comerciales desempeñan un papel importante por las economías de los países en vías de desarrollo, incluyendo los Países Terceros Mediterráneos (PTM). Desde los años ochenta, la apertura comercial de Marruecos se ha ido concretando mediante la firma de acuerdos de libre comercio con varios países y bloques comerciales (UE, USA, Turquía, países de Agadir¿). Con la mayoría de estos socios comerciales la balanza comercial general y agrícola de Marruecos se mantiene en términos deficitarios a pesar de los esfuerzos de competitividad y establecer el equilibrio.
La mayoría de las exportaciones agrícolas de los PTM se destinan al mercado europeo, sobre todo en las frutas y hortalizas, productos para los cuales disponen de ventajas comparativas y condiciones de acceso preferente. La literatura ha señalado que Marruecos recibe altos márgenes de preferencia por parte de la UE para sus frutas y hortalizas exportadas al mercado europeo.
Con esta situación, el objetivo principal de esta Tesis es analizar cuantitativamente las implicaciones para Marruecos de las preferencias actuales y de hipotéticas liberalizaciones comerciales futuras. Consecuentemente se realizan dos análisis complementarios. En primer lugar, se calcula el Valor del Margen de Preferencia para varias frutas y hortalizas de importancia en las exportaciones marroquíes a la UE (tomate, naranja, pepino y clementina), considerando el nuevo acuerdo comercial entre la UE y Marruecos. Los resultados obtenidos señalan que el tomate es el producto con mayor alcance de estas preferencias, que la reducción del precio de entrada tiene diferentes implicaciones prácticas entre estos productos, y que la revisión del acuerdo ha supuesto mayores transferencias potenciales para Marruecos.
En segundo lugar, en esta investigación se exploran diversas posibilidades de liberalización comercial de las importaciones de la UE para estos mismos productos, posibilidades que van desde una liberalización limitada a los productos marroquíes, a otras más generalizadas. Se realizan diversas simulaciones de equilibrio parcial teniendo en cuenta las peculiaridades de la protección comercial en frutas y hortalizas y diferentes orígenes de los productos. Los resultados de las mismas muestran caídas de precios en el mercado europeo y aumentos notables del volumen de las importaciones, y al mismo tiempo aumentos de los precios en frontera para el país exportador. Además, en todos los casos cabe destacar una pérdida en el bienestar de consumidor marroquí, y ganancias para los productores de este país.Ouabouch, H. (2013).

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
Les stratégies de commercialisation des produits de terroir agricole marocain : cas des dattes de la vallée de Draa
No full textThe objective of this article is to explain how producers and traders can maximize the value of Moroccan agricultural terroir products, such as dattes from the Drâa Valley, by adopting effective marketing strategies to better position them in markets and support sustainable development of terroirs based on social and solidarity economies. This analysis combines a quantitative study (survey administered to local actors: producers, cooperatives, traders, and distributors) with an empirical literature review, in order to identify the advantages and limitations of marketing strategies and propose practical recommendations.
The study highlights that Drâa Valley dattes have significant potential in both national and international markets, yet their commercialization is constrained by limited visibility, traditional distribution channels, and insufficient promotion and certification. The proposed recommendations focus on enhancing product quality through labels and certifications, modernizing distribution channels, developing digital marketing, and supporting local cooperative structures to ensure sustainable and responsible production.

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
