On the decay of solutions to the 2D Neumann exterior problem for the wave equation
No full textAbstractWe consider the exterior problem in the plane for the wave equation with a Neumann boundary condition and study the asymptotic behavior of the solution for large times. For possible application we are interested to show a decay estimate which does not involve weighted norms of the initial data. In the paper we prove such an estimate, by a combination of the estimate of the local energy decay and decay estimates for the free space solution
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
Proposals for OrderingKey DS instantiation in MPEG-7 description
No full textThis document identifies some solutions to the problem stated in the Editor’s Note in clause 7.7.1.1 of the MDS Study of CD, document ISO/IEC JTC 1/SC 29/WG 11/N3816. Therefore this document is intended as a contribution to the MDS group.
Presently there is no way to instantiate an Ordering Key DS within a “valid” MPEG-7 description.
To solve this problem three proposals are here considered and their respective implication are discussed. The first proposal is to derive the OrderingKeyType as an extension of the HeaderType allowing the instantiation, at the header level, of any MPEG-7 Complete/Unit Description and DSType instances. The second solution is to include the OrderingKey DS as a component of the BasicDescriptionType. This allows to apply the ordering tool only in an MPEG-7 Complete Description, but no Unit Description. The third solution is to adopt both the first and second proposals. In Section 2 the three solutions are detailed and the required modification in terms of syntax and usage are discussed. In Section 3 the three solutions are compared
Report on Ordering Key DS CE
No full textIn this document, we report the results of our core experiment on the Ordering Key D. The concept of the Ordering Key D has been proposed for the first time in Beijing meeting [m6227] as a part of the generic Weight DS. According to the discussions during that meeting the Weight DS has been specialized in order to obtain exclusively ordering functionalities [w3473]. At the same time the demo showed in Beijing seemed to demonstrate the useful of the ordering beetwen entities of various types. At the following meeting a specialized and improved semantic and syntax have been proposed. In spite of positive results about its utility, as shown in the demo [m6588] and also in the document [m6491], it was not clear the use of XPath syntax as mechanism to obtain reference to entities. At the La Baule meeting the DDL group had not yet decided about the use of XPath as reference datatype. In conclusion the aim of this CE was not to demonstrate the OrderingKey effectiveness but to investigate about its syntax [w3630]
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
