Desarrollo de una metodología de integración paisajística de las autopistas
No full textEl presente trabajo se enmarca dentro del proyecto “Operación de Autopistas Seguras, Inteligentes y Sostenibles (OASIS)”, cuyo principal objetivo es definir la autopista del futuro, aquella que en su operación presentará niveles notablemente altas de seguridad, servicio al usuario y sostenibilidad. Para lograrlo, uno de los parámetros a tener en cuenta es la conservación y optimización del paisaje por el que discurren. Esta tesis desarrolla una metodología de valoración del paisaje de las autopistas, aplicando dicha metodología a diversos tramos de las autopistas gestionadas por empresas del proyecto (OHL Concesiones, Iridium y Abertis). El estudio se ha llevado a cabo en más de 2.000 km de autopistas, identificando los diferentes paisajes vistos desde la carretera y elaborando un catálogo de fotografías digitalizadas y georreferenciadas de los paisajes; desarrollando y aplicando una novedosa metodología de valoración de la calidad del paisaje; determinando las diferencias entre el paisaje percibido desde las autopistas por medio de fotografías y mediante la utilización de mapas representativos de paisaje; identificando los elementos de diseño paisajístico (puentes, estaciones de servicio, etc.) y estableciendo alternativas para su mejor adecuación paisajística; y estimando el impacto que provocan estas infraestructuras al observarse desde fuera. Es de esperar que las conclusiones extraídas de este proyecto permitan una mejor integración paisajística de las autopistas del futuro, convirtiéndose en instrumentos para mostrar paisajes de mayor calidad, y reduciendo el impacto como elementos modificadores del territorio. Summary This work is within the framework of the project "Operation of Safe, Intelligent and Sustainable Highways (OASIS)," whose main objective is to define the highway of the future, which in its operation will present significantly high levels of safety, customer service and sustainability. To achieve this, one of the parameters to consider is landscape conservation and improvement along highways. This thesis develops a methodology for assessing the landscape of highways, applying the model to different stretches of highway managed by project companies (OHL Concessions, Iridium and Abertis). The study was carried out in more than 2.000 km of highways, identifying the different landscapes seen from the road and developing a catalog of digitized and georeferenced photographs of landscapes; developing and applying a new methodology for assessing the quality of the landscape; determining the differences between the landscape seen from highways through photographs and use of landscape maps; identifying the landscape design elements (bridges, service area, etc.) and providing alternatives for better landscape; and integration estimating the impact that cause these infrastructures when viewed from outside. It is expected that the conclusions extract from this project allow to better landscape integrate of the future highways, become instruments to show higher quality landscapes, reducing the impact as modifiers´ elements of the territory
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
