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
Investigation of wave transformation and breaking processes in the coastal zone using REEF3D
No full textSeveral human activities and industries that contribute in shaping the communities and economies around the world are located in the coastal zone. Therefore, it is very crucial to understand the behaviour of the coastal system to better evaluate the design choices related to the treatment of these areas.
Thanks to the rapid technological development in the computational domain, it is now possible to simulate the evolution of waves numerically to a great accuracy and evaluate their effects on the structures. In this thesis, the main goal is to numerically model the evolution and breaking of waves using the open-source CFD model REEF3D and compare the results to field data obtained with LiDAR and ADV sensors.
The novelty of this work lies in modelling a large scale field case with a CFD model in contrast to shallow water or phase-based models. Moreover, the accuracy of the results is improved by using wave reconstruction method in the generation of the incoming wave boundary and the application of non-uniform grids. \\
The complexity of simulating waves in the field lies in the numerous contributing variables that can not be controlled in a measurement campaign. The irregularity of the phases, directions and frequencies of the waves and their evolution on a three dimensional irregular bathymetry increase the difficulty of the task. Consequently, some bench-marking simpler cases will be investigated first and will be compared to laboratory monitored experiments to have confidence in the CFD model and to understand the underlying physics of the problem.
In the first case, the run-up of a solitary wave on a constant slope is compared to a laboratory experiment. In the second case, regular waves will be imposed on a constant slope and the plunging breaking behavior will be compared to a laboratory experiment. The third case will investigate the behavior of irregular waves on an experimental irregular slope and lastly the field case will be tackled and compared to field measurements
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
