Tsunami Deposits and Their Morphological Effects: A Regional Scale Approach
No full textTsunami are high energy events which have heavy morphological
impacts on the shore lines. A review of the literature shows that these impacts are
very difficult to differentiate from large storms impacts in most of the cases.
This paper begins with a description of tsunami impacts, at a local scale, in terms
of erosion and of accumulation. It studies cases where tsunami accelerate “normal”
behaviour of the coast or, on the other hand go against expected normal behaviour.
In order to better understand the relative roles of tsunamis and storms, the local
forms are replaced within a regional scale/context and some important regions
(Mediterranean Sea, New Zealand, the Antilles) are taken as examples of the
interrelation between storm-forced evolution and tsunami – controlled behaviour
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
Polygenic (tsunami and storm) deposits? A case study from Ushant Island, western France
No full textUshant Island is the westernmost island offshore western France. It is exposed to severe storms. The western peninsulas of the island are partly covered with boulder fields, the origin of which is an open question. On March 10, 2008 a very severe storm (973 hPa) was able to move some of these blocks and to raft them over several tens of meters. The heaviest block weighs about 62 tons. Some blocks were located in the intertidal zone, others were above the spring tide limit and were detached from the cliff during the storm. Most of the blocks had already existed before; thus, the event which actually caused their detachment was not the March 2008 storm. When applied to this case, the hydro-dynamical equations by NOTT would suggest a storm with wave heights of 12 to 50 meters. New equations by the authors reduce these values to about 8 to 32 meters. Anyhow, these heights have never been recorded in Ushant. These results thus lead to the hypothesis that the blocks were not created by a storm but by a tsunami, possibly the one of 1755 (Lisbon Tsunami). The important point is that these blocks have a polygenetic origin: they were detached from their initial location by an event which cannot have been a storm, but subsequently they were moved by each severe storm. Boulder fields on Ushant Island, therefore, seem to be polygenetic coastal high energy event features
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
