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
Assessment of liquefaction triggering by seismic dilatometer tests: comparison between semi-empirical approaches and non-linear dynamic analyses
No full textThe evaluation of soil liquefaction potential can be assessed using approaches with an increasing level of complexity. In engineering practice, the most common method is based on the use of empirical charts where the soil cyclic resistance is correlated to the soil resistance as measured in field tests, such as standard penetration test (SPT) and cone penetration test (CPT). Similarly, also seismic dilatometer tests (SDMT) can be used to assess the potential triggering of liquefaction in soil deposits as already shown in several case studies in Italy and around the world. In the present study, the results of seismic dilatometer tests carried out along a sketch of a river dyke highly damaged by the 2012 Emilia Earthquake have been used to assess the liquefaction potential of the embankment and the foundation deposits, using semi-empirical methods and dynamic analysis. Both methodologies highlighted high liquefaction risk for the investigated soils which is also compatible with the results obtained by more sophisticated non-linear dynamic analysis of the dyke carried out in effective stress condition. Finally, the advantages and limitations of the adopted approaches are discussed and practical guidelines are provided for SDMT-based methods
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
Numerical analysis of the nonlinear behaviour of a masonry building undergoing slow-moving landslide-induced displacements
No full textThe paper shows the preliminary results of a numerical analysis aimed at investigating the response – in terms of onset and development of damage – of a masonry building with shallow foundations undergoing slow-moving landslide-induced displacements. The analysis is performed by applying the Equivalent Frame method to a representative damaged masonry building located in the historic centre of Lungro town (Calabria region, southern Italy) interacting with a slow-moving landslide in complex-structured and weathered soils. A three-dimensional settlement pattern is imposed at the foundation level by way of a displacement-controlled analysis that makes use of both vertical and horizontal displacement information gathered from conventional (ground-based) and innovative (remote-sensing) monitoring techniques. The obtained outcomes, owing to the good matching of the modeled building response with damage data collected by multi-temporal in-situ surveys, can help in defining representative building-landslide models to be used for predicting and preventing the damage in slow-moving landslide-affected urban areas
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
