A coupled LES and observational approach to improve measurements of ocean turbulence from gliders
No full textMicrostructure-equipped autonomous ocean gliders are proving to be an adequate platform for measuring turbulence with the advantage of extended duration and fine resolution measurements. However, it is still unclear how the movement of the glider platform impacts the flow around the attached sensors. The incident along-glider water velocity is not known but essential for the calculation of dissipation rates as errors introduce a significant bias. Steady-state or dynamical flight modules that incorporate all significant forces are required to compute the set of parameters that subsequently can be used for calculating turbulent dissipation rates. In our investigations, we provide more evidence for this method with the help of computational fluid dynamics (CFD) simulations with the large eddy simulation (LES) approach of the flow aroundthe glider and its sensors so that the bias in the velocity flow measurements can be estimated.Through velocity measurements, velocity shear and therefore turbulent dissipation rates can be determined which are calculated for various ambient dissipation rates eam ranging from 10􀀀11m2s􀀀3 to 10􀀀6m2s􀀀3, thus covering the known range of possible and measurable turbulent motion around the world. This enables our study to investigatethe current limits of turbulence measurement on the glider platform and advises caution for the application of glider-based turbulence measurements in low-energetic (i.e. Arctic Ocean) or featureless abyssal plains of the oceans. For high levels of turbulence with the ambient dissipation rate greater than 10􀀀9m2s􀀀3 our results of the flow simulation indicate only small effects of the self-induced strain rate with a ratio less than 1.5 comparing the measured dissipation rate emeas in the simulation with the ambient dissipation rate.These results attest the glider platforms suitability for turbulence measurements in most areas around the world but also indicate an underestimation of measured flow speeds around the probe tips of the microstructure probe by up to 15%, which should be taken into account for the calculation of turbulent dissipation rates
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
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
