Participative Agri-Food Projects in the Urban Bioregion of the Vega of Granada (Spain)
No full textThe Vega of Granada is a traditional peri-urban agricultural bioregion that includes important environmental and heritage values. As it belongs to the urban agglomeration of Granada, the agricultural land has been affected by the urban sprawl and other impacts of the contemporary metropolitan model. The strategic position of this fertile land and the growing interes in local and organic food products give an opportunity to the Vega of Granada to recover the basic role that it played before the new trends imposed by the global food system. Following to a bioregional approach, this chapter explains some of the participative processes that were activated to develop the alternative food system, mainly considering the use of short food supply chains to distribute and sell the agricultural products of the Vega of Granada. The success of some of those activities and the increase in the consumption of local products demonstrate the importance of participation as a key question in relocalising the food systems and increase the resilience of the peri-urban agricultural land.Depto. de GeografíaFac. de Geografía e HistoriaTRUEpu
La investigación científica y el desarrollo sostenible de la amazonía peruana
Full text linkIdentifica dos grandes preocupaciones respecto a la biodiversidad, que están afectando el desarrollo socioeconómico de los pobladores de nuestra región: La primera, es la pérdida de diversidad biológica por causa de la pérdida de hábitats, sobreexplotación y erosión genéca en las especies, lo que pone de manifiesto la importancia de programas de conservación e invesgación cienfica en diferentes líneas para el desarrollo agropecuario, forestal e industrial. La segunda preocupación se refiere a la heterogeneidad cultural del territorio y la desaparición de numerosas etnias, lo que lleva a la pérdida de conocimientos
tradicionales sobre recursos genécos y práccas de manejo sostenible de los ecosistemas. Asimismo, existe una preocupación muy grande respecto a la ausencia de invesgación básica sobre la diversidad biológica, y sobre productos potencialmente interesantes con valor agregado. Una muestra de ello es el poco interés de los organismos estatales que corresponden para asignar mayores presupuestos para invesgación cienfica en las universidades estatales o públicas sustentado en el marco de la Ley 30220 (Ley
Universitaria, que imperavamente obliga a la academia ser generadora de conocimiento). Otra de las amenazas para la diversidad biológica es la falta de polícas para una mejor orientación de crecimiento demográfico. Además, dada la estrecha relación con diversas acvidades económicas, existen otras polícas que afectan el uso de los recursos. Los problemas existentes enen que ver también con los recursos humanos. La información que ene la población sobre la candad y valor de su diversidad es muy reducida, excepto
por comunidades o etnias locales, lo que evidencia la necesidad de incorporar en el sistema educavo aspectos relavos a la conservación y uso sostenible de la diversidad biológica. Por otra parte, se requiere contar con el financiamiento necesario que permita realizar invesgaciones cienficas. El presente ensayo aborda esta problemáca, y desde el aporte de la invesgación cienfica muldisciplinaria se proponen estrategias de polícas públicas para el
desarrollo sostenible de la Amazonía, que se espera sean aportes a tener en cuenta.introducción -- El rol de la investigación científica en la formación profesional y en el desarrollo de la Amazonía -- La Amazonía peruana.

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
