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
On the design and construction of stone masonry bridges : comprehensive review of traditional literature-based techniques and practical applications to current professional projects
No full textStone masonry bridges represent a significant portion of existing in-service bridges in Europe. Furthermore, since such type of bridges is no longer used for new constructions, their study (from the configuration, structural and construction points of view) has been forgotten or overlooked. However, a thorough understanding of their design and construction is essential to appropriately assessing, maintaining, rehabilitating and preserving these valuable structures. Unfortunately, relevant literature is fragmented and incomplete, leaving existing masonry bridges orphaned of doctrine and of treatment in modern codes. Based on a comprehensive review of European treatises (especially Spanish) published in the 16th through the 19th centuries, this thesis begins to mend the knowledge gap by summarizing the main aspects involved in the design and construction of stone masonry bridges. A particular emphasis is also given to the auxiliary tools used, in particular centrings, exploring their function and behaviour in bridge construction. Then, the techniques provided by ancient treatises are combined with modern construction technologies. Thus, a detailed study on the strengthening technique of the saddling is showed, and then, the rehabilitation processes of the Langa de Duero bridge and the Deba bridge (both in Spain) are illustrated, providing valuable references for practitioners and researchers interested in this topic.
This thesis bridges a gap in the technical literature that is mainly focused on analysis techniques, and scarce works are addressed to the (re)construction process of masonry bridges or a study of their original design and construction techniques. Thus, the investigation recovers valuable lost knowledge and serves as a basis for further research, with the ultimate aim of preparing modern engineers to intervene appropriately towards preserving the functional and architectural value of heritage bridges.
RESUMEN
Los puentes de piedra (o ladrillo) son representativos de una parte muy significativa de los que siguen prestando servicio en Europa. Sin embargo, como ya no se construyen puentes así, el conocimiento de su configuración estructural y constructiva ha caído en el olvido, a pesar de ser indiscutible que comprender en profundidad cómo son, cómo funcionan y cómo se construyeron es esencial para evaluar, mantener, rehabilitar, preservar y amar (por qué no) adecuadamente estas valiosas construcciones. Desgraciadamente, la literatura técnica sobre esta materia está fragmentada y es incompleta, dejando a los puentes de fábrica huérfanos de doctrina y tratamiento en los códigos modernos. Basándose en una revisión exhaustiva de tratados europeos (especialmente españoles) publicados entre los siglos XVI y XIX, esta tesis pretende ocupar parte de este vacío de conocimiento, en primer lugar, resumiendo de manera actualizada los criterios de diseño y construcción de puentes de fábrica. Especial énfasis se otorga también a los medios auxiliares, en particular a las cimbras, explorando su función y comportamiento en la construcción de puentes. Además, se presenta cómo las técnicas proporcionadas por los tratados antiguos se combinan con las tecnologías de construcción modernas para aplicaciones a proyectos reales. Se muestra, a título de ejemplo, un estudio detallado sobre la técnica de refuerzo mediante el ensillado, ilustrado sucesivamente en los procesos de rehabilitación del puente de Langa de Duero y del puente de Deba (ambos en España), proporcionando valiosas referencias para profesionales e investigadores interesados en este tema.
Esta tesis pretende colmar una laguna en la literatura, que se centra principalmente en técnicas de análisis, y son escasos los trabajos que abordan el proceso de (re)construcción de puentes de fábrica o el estudio de sus técnicas originales de proyecto y construcción. Por lo tanto, la investigación recupera valiosos conocimientos perdidos y sirve como base para investigaciones futuras, con el objetivo final de dotar a los ingenieros modernos de doctrina para intervenir adecuadamente en la preservación del valor funcional y arquitectónico de los puentes de fábrica, elementos esenciales de nuestro patrimonio
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
